Baryon-dominated dwarf galaxies (BDDGs) can emerge from high-velocity collisions between gas-rich ultra-diffuse galaxies. Using hydrodynamical simulations with progenitors of contrasting gravitational binding energies, we show that progenitor structure critically regulates BDDG formation. Specifically, collisions involving more weakly bound progenitors sustain star formation longer and yield...

The Milky Way Survey of the Dark Energy Spectroscopic Instrument (DESI) has so far observed three classical dwarf spheroidal galaxies (dSphs): Draco, Sextans and Ursa Minor. Based on the observed line-of-sight velocities and metallicities of their member stars, we apply the axisymmetric Jeans Anisotropic Multi-Gaussian Expansion modeling (JAM) approach to recover their inner dark matter...
